Specification of Letters Patent.

Patented Dec. 11, 1906.

Application filed August 3, 1905. Serial No. 272.450.

To all whom, it may concern:

Be it known that I, ANDREW HAUG, residing at 1965 Madison avenue, borough of Manhattan, city,'county, and State of New York, have invented certain Improvements in Sound-Re roducers, of which the followingwis a speci 'cation.

p y invention relates to sound recording and reproducing apparatus in eneral, and as herein embodied is designed or use in connection with sound-reproducers of the type employing a detachable needle or stylus.

The object of my invention is primarily to produce a device which will operate automatically or semi-automatically to detach ably securethe needle or stylus in locked relation with the stylusarm, and thereby disense with the old form of set-screw heretoiore employed for this urpose.

A further object 0 the invention is to cause such a device to perform a double function, the first being to secure the stylus in position, as above stated, and the second to coact with the stylus-arm and maintain it in operative relation to the diaphragm under the required tension.

A device suitable for carryi tion into effect is illustrated in tie accom anying drawings. I do not wish to be un erstood, however, as limiting myself to either the exact construction or arrangement shown, as various changes may be made therein without departing from the spirit and scope of my invention.

In the drawings, Figure 1 is a central section of a sound-re reducer, showing my invention a lied t ereto. Fig. 2 is a top view; and 1g. 3 is a side elevation thereof.

Referring now to the drawings, 1 represents the casing of the re roducer or sound-box, as it is generally own, 2 the diaphragm mounted therein, and 3 the stylus-ann,wh1ch is pivoted at 4 or otherwise operatively arranged with the inner end thereof connected to the diaphragm. The stylus-arm is socketed at its free end in the usual manner, as indicated at 5, to receive a needle 3, whichis detachably held therein by a spring 6.

The form and arrangement of the spring may be varied in accordance with the re-' guirements of the particular t e of re roucer with which it is used. referab y a my invenplate-spring is employed having one end 7 thereof secured in a recess 8 of the casing and the o posite end 9 bent-u to extend across and s ightly in advance 0 the socketed end of the stylus-arm. Formed in the spring at a point slightly out of line with the socket of the stylus-arm there is an aperture 10, which i s elongated or given a V form, as shown.

When a needle is to be inserted, slight pressure of the finger upon the spring serves to bring the aperture 10 thereof into alinement with the socket of the stylus-arm, permitting the needle to be passed through the aperture and enter the socket in the usual manner. i As the s ring is released it tends to return to norma position; but its movement is checked by the needle, which becomes firmly ipped under the pressure of the spring in t e small end of the V-opening thereof. The removal of the needle is readily effected, as will be apparent, by depress ing the spring until the V ortion of the aperture clears thesame,andt ereu onthe needle falls out of the socket of the sty us-arm by its own wei ht.

In ad ition to its function oflocking-the needle in position the spring also acts through the same to exert sufficient pressure upon t e stylus-arm to maintain its inner end in operative relation to the diaphragm under the required tension.

The free end of the spring is referably bent over, as shown,-to serve as a ger-rest for convenience in depressing the same as required to insert or release a needle. The movement of the spring is limited by a suit able stop 11, which prevents its being bent out of shape or broken.

The extreme sim licity and effectiveness of .the device, as we 1 as its many important advantages, will be at once apparent.

Having thus described my invention, I claim 1. .A sound-reproducer comprisin a casing, a diaphragm therein, a pivote stylusarm, a spring normally meiiectlve, anda stylus through which the spring acts to maintain the arm in operative relation to the diaphragm.

- 2. A sound-reproducer com rising a casing, a diaphragm therein, a sty us-arm socketed at one end, a spring arranged exteriorly of the socket and acting'in a line at right angles thereto, andastylus movable-in and out 1 in-opposition to the s' ring. 3. A 'sound-reproducer com rising a .cas-

ing, a diaphragm therein, 'a, sockete of the socket in opposition to the spring;

ing, a diaphragm therein, a sty us-arm 'soclk eted at one end, aspring arrange-d exteriorly of thesocket and extending across the open end thereof, and a stylus movable in'and out of the socket in opposition to the spring 4. A sound-repro'ducer comprisin L a -c'a,s-,

ing, a diaphragrntherein, .a sockete -stylu s rin provided with an openin ecarm, a sp r lsposed to the open end 0 the the socket in opposition to thespring.

5 A'sound-reproducer comprising a was ing, a diaphragm therein, a socketed stylus arm, an apertured spring, said armand spring being relatively arranged normally with the socket and aperture thereof out of alinement,

and a stylus movable in andout of the socket in opposition to the s ring] 6-. 'Afsound-reprodiilcer comprisin a casing, a diaphragm therein, a sockete stylusarm, a spring arranged exteriorly to the socket and-controlling entrance to the same and .a stylus movable 1n and out of the sookei a casstylusarm, a spring having an 'ap roximately V- shaped opening therein, sald opening'being 7. A sound-repro ucer comprising normally out of alinement. with the socket in the arm, a stop for limiting movement of the spring, and a stylus adaptedtc enter the socket through the opening'in the spring.

8. A'soundsreproducer comprising a casing, a diaphragm therein, a socketed stylusarm, a spring' having an approximately V- shaped opening therein, the smaller end of the opening registering normally with the open end of the socket 111 the arm,'and' a stylus adapted to enter the socket and interlock with the opening in the sprin In testimony whereof I fl ix In in the presence of two Witnesses.

ANDREW HAUG.
